Many devises need more power to start up (Maximum Output Watts) and then require less power (Rated Watts) to run continually. For example, a refrigerator requires 2200 starting wattage with a 700 running wattage, so you would need a generator with at least 2200 watt maximum output.
Considering this, how many watts is a typical refrigerator?
Find the voltage and amperage of the refrigerator; for instance, you may see "115 V" and "6.5 amps." Multiplying these two numbers tells you how many watts your refrigerator uses -- in this case, 747.5 watts. Smaller refrigerators typically use about 350 watts, while larger models use as much as 780 watts.
What is the wattage rating?
The Resistor Power Rating is sometimes called the Resistors Wattage Rating and is defined as the amount of heat that a resistive element can dissipate for an indefinite period of time without degrading its performance.
Do old refrigerators use a lot of electricity?
A 1986-era 18 c.f. fridge uses 1400 kWh a year, while a modern energy-efficient model uses only 350 kWh — a whopping 75% reduction. At 15¢ kWh, trading in a pre-1986 fridge for a new efficient one would save about $158 a year in electricity costs. And some older fridges are even worse than the average.
